Due to the recent increase in the concentration of heavy metals in urban bodies of waters in the Philippines due to industrialization, the study sought to determine ideal methods of adsorbing these substances and prevent them from posing adverse health effects to surrounding communities. The method in the study reviewed the literature on using water hyacinth biomass as an adsorbent of heavy metals, specifically copper (II) or Cu(II), in contaminated areas susceptible to polluted wastewater runoff. With this, the ideal adsorbent was determined through factors of particle size, initial ion concentration, adsorption time, ideal conditions, and the adsorbent structure. From the reviewed studies, water hyacinth is an effective biosorbent for copper ions and can reduce copper concentrations in wastewater bodies. Ideal factors for maximum adsorption in terms of wastewater characteristics were conclusive amongst the chosen literature. Other parameters, however, require further investigation to determine if there are trends in how they affect adsorption capacity and removal percentage of the biomass.
